Definitions
- the invention relates to a method for removing dust from the face of a catalyst made of ceramic material for the purification of a gas stream.
- a rotary tube which is guided centrally in bearings and which opens at one end into a suction tube and at its other end with a transversely arranged tube with a slot-like configuration and extending essentially over the entire diameter of the gas channel Approach is connected.
- This rotary tube is driven by a motor arranged outside the gas duct via a shaft and a gear consisting of worm and worm wheel.
- the suction pipe is connected to a blower by means of to which the extracted amount of gas is supplied to a dedusting device.
- the embodiment according to FIG. 1 is a gas channel (1) with a circular cross-section, in which a catalyst (6) with a lattice structure is arranged, ie with a plurality of channels (12) which are separated from one another by webs (11) .
- the end faces of the webs (11) together form the inflow surface of the catalyst (6), which is perpendicular to the gas flow and therefore inevitably causes dust deposits.
- a tube (5) which extends essentially over the entire diameter of the channel and has a slot-like extension (10) which is connected to a rotary tube (8).
- the rotary tube (8) is rotatably mounted in bearings (7) and can be driven via a motor (3) by means of a shaft (4) and a gear (9) consisting of worm and worm wheel.
- the rotary tube (8) opens into a stationary suction tube (2) which is connected to a blower, not shown.
- the pipe (5) with the slot-like extension (10) has the cross section shown in Figure 2.
- the lattice structure of the catalyst (6), the webs (11) and the channels (12) can be seen from FIG. 3.
